SPECIFICATION forming part of Letters Patent No. 761,830, dated June *7, 1904. Application 518a Ma 19, i903. Serial No. 157,865. (No model.)

To aZZ whom it may concern.-

Be it known that I, J ESSE EDWARD HARRI- SON, a citizen of the United States, residing at Wetaskiwin, in the district of Alberta, N orth- VVest Territories, and Dominion of Canada, have invented certain new and useful Improvements in Grain or Hay Elevators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and

to. the letters of reference marked thereon,

which form a part of this specificationn This invention relates to new and useful improvements in hay-elevating apparatus; and the object of the invention is to provide a machine for raising the grain from the ground and depositing the same upon a conveyor, whereby it may be carried and delivered to one side of the apparatus. 7

The invention consists, further, in various d etails of construction and combinations and arrangements of parts, which will be hereinafter the forked members for raising the hay or grain. Fig. 5 is an enlarged detail view of one of the rotary beaters, and Fig. 6 is an edge view of the form shown in Fig. 5. Fig. 7 is a sectional view taken on line 7 7 of, Fig. 1.

Reference nowlbeing had to the details of the drawings by letter, A designates the frame of a truck having a shaft B journaled in suitable bearings therein, and B designates driving-wheels which rotate with said shaft, and G designates apinion-wheel keyed to rotate with the shaft 13. Journaled in the plates D, forming a part of the superstructure of the frame of the truck, are the shafts E and E, the former of which has pivotally connected to the crank thereon the angled links F, there being two of these links, one on either side of the apparatus, the other ends of which are connected to the shaft H.

g F designates links which are loosely journaled upon the shaft E and their other ends pivotally connected to the arms Gr, each of said arms having plvotal connection with a crank H on a crank-shaft H which latter is journaled in links K, there being one on each side of the frame, and each of said links K is pivoted at K upon a portion of the frame of the apparatus. (Shown clearly in Fig. 2 of the drawings.) The end of each arm Gr has a fork G, a detail view of one of said forks being shown in Fig. 4 of the drawings. The several cranks H of the shaft H are disposed. at angles to each other which will cause the various forks to be successively brought into engagement with the material to be hoisted upon the loader as the shaft His rotated by gear-wheel H thereon meshing wit-h a pinion H, driven by a sprocket-wheel having chain connection H? with a sprocket-wheel on the main driving-shaft B. One end of said shaft E is bent to form a crank-arm E and pivoted to said arm E is arod E, which extends rearward to the standard E engages a slot in the latter, and has a'portion bent to forma handle and adapted toengage behind said standardfor the purpose of limiting the forward throw of said rod. Mounted upon the truck of said apparatus is an adjustable endless conveyer I, comprising an endless chain turning about the sprocket-wheels I, one of which is shown in Fig. 2 of the drawings. Said conveyer is mounted upon the suitably-journaled shafts J and J, the latter having fixed to one end thereof a pinion J which is in mesh with the gear-wheel C. The rear end of the conveyor I is mounted to travel about sprocket-wheels J rotating with the shaft J. To the opposite sides of the endless conveyor 1 are pivotally connected the links N, one of which is'shown in Fig. 2 of the drawnigs, the upper ends of said links N being pivotally connected to the crankarms N, which are integral with the shaft E. Said shaft E also is provided with a crankarm l which is pivotally connected to a rod Niwhich has near its free end a portion N bent to form a handle and adapted to engage behind said slotted standard E. Said rod N is provided for the purpose of raising and lowering the outer end of the conveyor I, the handle ends of said rods E and N both being within convenient reach of the operator.'

Said standard E is mounted upon the tongue A, having a suitable evener A, the rear end of which is supported by means of acaster-wheel A mounted on a yoke A, the shank portion of which is journaled in an aperture near the end of the tongue, and a guiding-tiller A is secured near the upper end of said shank portion and is convenient to the platform on which the operator stands, whereby the apparatus may be guided. It is my purpose to attach to the tongue at any convenient location an evener to which the team may be connected along each side of the tongue A, whereby the apparatus may be pushed in advance of the team.

A horizontally-disposed conveyer M is provided, which travels about sprocket-wheels mounted upon the shafts O and O, which endless conveyer is driven by means of the bevel gear-wheel O fixed to the shaft which is in mesh with a bevel-gear O fixed to rotate with the shaft O journaled in the frame, said shaft O carrying a pinion P, in mesh with a pinion P on the driving-shaft B. A pinion-wheel O journaled on the frame, meshes with pinion O and also with pinion 0 on the shaft 0 whereby power may be transmitted to the conveyers M and Q and the conveyer Q is disposed at an angle, as

seen in Fig. 7, and passes about suitable sprocket-wheels driven by the sprocket-chain O", traveling about the sprocket-wheels, one of which is mounted upon the shaftO and the other upon said shaft 0 Mounted upon the vertically-disposed shafts B (there being two, one upon each side of the truck) are the beater members S, detail views the same.

of which are shown in Figs. 5 and 6 of the drawings, and having wings which are adapted to throwthe grain or hay toward each other upon the adjustable conveyer between The lower ends of said shafts R have bevel gear-wheels R, which are in mesh with similar pinion-wheels R fixed to rotate with the shafts T, the other ends of said shafts T, having bevel-pinions T, vhich are in mesh with pinions T, which rotate with the shafts J and O respectively.

The operation of my apparatus is as follows: The team, being hitched to the evener upon the tongue, which extends rearward from the apparatus, is driven forward adjacent to the sheaves which have been shocked up, or along windrows if the elevator is used for hoisting hay, and the driving-wheels will cause the shafts carrying the same to impart a rotary movement to the crank-shaft H, which will cause the forks to be actuated in such a manner as to cause the free ends thereof to pick up the grain or hay and throw it forward upon the conveyor 1. As said conveyer is in geared connections with the otherelevators, any grain or hay that may be deposited upon the sameby the forks will be carried rearward and will fall upon the horizontally-dis posed conveyerM and from the latter will he carried to and dropped upon the inclined elevator Q, which may be of any desired construction adapted to elevate the grain up the incline and drop the same over the end thereof into a wagon-box, which may be positioned adjacent to and along the side of the grain-elevator. By the provision of the rods with hair dle ends adjacent to the platform upon which the operator stands the shafts carrying the forked members may be raised and lowered, and also the conveyer I may be raised and lowered in order to adapt the apparatus to uneven ground and for the purpose of adjusting the forked members and the conveyor to work in connection with high or low shocks or windrows of hay, as the case may be, and by means of the caster-wheel and the tiller the operator may with his legs throw the same one way or the other to guide the apparatus in its forward movement.

While 1 have shown a particular construction of apparatus embodying my invention, it will be understood that 1 may make changes in the detailed construction of the elevating apparatus without departing from the spirit of the invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
